SPECIFICATION forming part of Letters Patent No. 731,288, dated J une 16, 1903.J Application filed May 23,1902. Serialllo. 108,653. (No model.)

To all whom it may concern: Be it known that I, ANTONIO DELLANNA, a citizen of the United States, and a resident of Salt Lake City, in the county of Salt Lake and characteristic of which is one or more cylinders moving on relatively stationary pistons and adapted to be submerged in a body of water to force a column through a dischargepipe.

The invention involves certain novel features of structure and arrangement which will be fully described hereinafter.

This specification is an exact description of one example of myinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding' parts in all the views.

Figure 1 is a side elevation of the invention with parts broken away. Fig. 2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a section on the line 3 3 of Fig. 1.

The apparatus comprises a base. 10,.at eachv vertically in parallelism with` each. other.

The base 10 is adapted to be sunk to the bottom of the body of water in which the pump works, and the stanchions 11 rise above the level of the surface thereof, as the drawings show. The stanchions `are braced together to form a rigid structure by means of transverse shafts 12, extending between them, and side braces 14c are also provided.

Between the stanchions 11 and carried to swing around the shafts 12 are pairs of walking-beams 15. The uppermost and lowermost pairs of .walking-beams 15 are connected at each side of the shafts 12 by means of rods 16, thus causing the said walking-beams to move in unison, and the uppermost pair of walking-beams has extensions 17, between which extends a handle-bar 1S, which permits the manual or other operation of the pump by swinging the said uppermost walkingbeams around the center of the uppermost shaft 12.

19rep1esents the pump-cylinders, which are preferably two in number, and 2O represents continuations of the pump-cylinders, forming chambers in which the piston-rods 421a're allowed to play idly.

22 indicates the pistons, these elements working in the cylinders 19 and being connected to the rods 21, which rods pass upward through stuffing-boxes 23 in the upper ends of the cylinders 19. At the bottom of each cylinder 19 is a footvalve 24., and from the lower portions of the cylinders extend by-pass pipes 25, that lead upward above the chambers 2O and into the discharge-pipes 26, which pass upward in alinement with the respective cylinders 19, as best shown in Fig. 2.

27 indicates a check-valve placed in the lower portion of each by-pass pipe 25.

The parts 19, 20, 25, and 26 are supported to move alternately up and down by means of the walking-beams 15, to which beams said partsare connected, at the ends of the beams,

4son and one cylinder, with its appurtenant parts, is lowered, while the other is being raised, and vice versa.

Fastened lto the braces 14 or to other suitable parts of the framing of the apparatus are. cross or transverse bars 2S, which carry rigidly two rods 29, these rods extending horizontally in parallelism with each other through vertical slots 30 in the walls of the chambers 2O "and through looped or split portions 1Ga of the rods 16. Thepiston-rods 21 have loops 31 formed therein, and through these loops pass the rods 29. 32 indicates rollers which are carried in the loops 31 of the rods 21 and which lie between the rods 29. These parts serve to hold the rods 21 and the attached pistons 22 effectively against vertical movement; butthey allow the said parts to move slightly sidewise to account for the slight sidewise movement of the cylinders 19, due to the swinging of the walking-beams 15.

33 indicates vent-pipes which pass to the atmosphere from the upper portions of the cylinders 19 and which serve to prevent compression within these cylinders.

In the operation of the apparatus the cylinders, with their attached parts, are caused IOO to move up and down, as bei'ore explained; but the pistons are held stationary by the partsin connection -with the piston-rods. On the downward movement of thc cylinders water enters below the pistons through the -33 are provided.

Various changes in the form and details of my invention may be resorted to at will without departing from the spirit of my invention. Hence I consider myself entitled to all i'orms of the invention as may lie within the intent of my claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A pump, comprising a cylinder, means mounting the cylinder to move longitudinally, a relatively stationary piston held in the cylinder, and a transversely-disposed guide slidably connected with the piston-rod to allow lateral movement of the piston.

2. The combination oi a walking-beam, a cylinder held thereby, a piston fitted in the cylinder, a rod attached to the piston, a guide, and means for connecting the piston-rod with the guide to allow the rod to move sidewise, for the purpose specified.

3. A pump, comprising a relatively stationary piston, a cylinder arranged to move on the piston, a rod to which the piston is joined, walls forming a chamber above the cylinder, into which chamber the rod extends, and means extending through the chamber and having connection with the rod to hold the same against longitudinal movement, said means allowing the rod a slight lateral movement, for the purpose speciiied.

et. A pump, comprising a relatively stationary piston, a cylinder arranged to move on the piston, a rod to which the piston is joined, walls forming a chamber above the cylinder, into which chamber the rod extends, means extending through the chamber and having connection with the rod, to hold the saine against longitudinal movement, said means allowing the rod a slight lateral movement, for the purpose specified, a discharge-pipe, a by-pass pipe passing from the lower portion of the cylinder around the said walls forming the chamber and into the dischargepipe, and valves commanding the cylinder and by-pass pipe.

5. A submerged pump, comprising a reciprocating cylinder, a stationary piston working therein, a discharge-pipe passing from the lower end of the cylinder, valves controlling the water-passage, the upper end of the cylinder being closed to the water, and a ventpipe passing from said upper end of the cylinder to a point above the water-level, for the purpose specified.

(l. In a pump, the combination with a support, of a walking-beam mounted thereon, a pump-cylinder mounted at one end of the walking-beam to be moved thereby longitudinally of the cylinder, a piston in the cylinder, a rod connected with the piston, and a horizontally-disposed guide arranged adjacent to the cylinder, with which guide the rod has sliding connection.
